The Greens candidate for the Upper House seat of Eastern Region, Cheryl Wragg, has been disendorsed.

Ms Wragg was disendorsed after clashing with Greens MP Greg Barber over the Greens policy in relation to the closure of Hazelwood Power Station.

Ms Wragg, who describes herself as an 'industrial green', says Mr Barber has put foward an energy policy that is "technically incompetent" and does not represent the views of Greens members.

"It has been a concern across various people in the party who know about energy policy that Mr Barber has been out promoting things that are simply unachievable," she says.

"It's not possible to close down Hazelwood Power Station in four years. It is not possible to replace its base load generation capacity with renewables and no, it is not possible to meet the problems of peak demands by more photovoltaic."
